摘要：研究了掺杂有机蓝光染料TPB的PVK薄膜的发光特性, 通过对掺杂薄膜的吸收光谱、激发光谱及发射光谱的分析，研究了 PVK与Alq₃之间的能量传递规律。当掺杂浓度为5%时，能量传递效率最高。用一个由单链模型扩展到包括杂质的哈密顿量对实验进行模拟，发现该模型能够较好地解释有关的实验结果。

Abstract：The energy transfer between PVK and TPB in PVK:TPB thin film in different concentrations was studied by emission spectra, excitation spectra, and absorption spectra. It is proved that the energy can be transfered from PVK to TPB in a wide concentration range and the transfer is most efficient at the concentration of 5% wt. A model Hamitonian based on a single chain model including the dopant was proposed to simulate the experiment. This model can be used to explain the experimental results very well.

Key words：Absorption spectra;Excitation spectra;Emission spectra;Energy transfer
